I felt that this box was gifted to you, it meant a lot to you and there were some beautiful artefacts in it earlier probably a snowglobe.
Later now you have kept some memories in it some cards, pictures, letters, scrapbooks...
That's interesting... The box was a gift from my mother. I don't think I ever put a snowglobe inside- although my mother might have, I don't know- but I did have spherical objects in it for a long time (specifically the head of a papercraft project I never finished). I also used it to store printed papercraft templates- the sheets of paper the individual pieces were on.
I took all that out and put something else inside for this, though.
